         8 . A method for manufacturing a patient interface, comprising:
 molding a cushioning structure including at least one chamber adapted to be filled with at least one filling material and a seal forming structure including a thin membrane flap in one piece with the cushioning structure with LSR,   filling the at least one chamber with at least one filling material; and   molding a cap and attaching the cap to the cushioning structure to enclose the at least one chamber.   
     
     
         9 . A patient interface, comprising:
 a polyurethane skin including at least one chamber filled with gel,   wherein the polyurethane skin includes an end portion that is oriented or curved inwardly to promote bending or rolling inwards towards the breathing cavity when force is applied thereto in use.   
     
     
         10 . A method for manufacturing a patient interface, comprising:
 vacuum forming a polyurethane skin including at least one chamber adapted to be filled with gel and an end portion that is oriented or curved inwardly to promote bending or rolling inwards towards the breathing cavity when force is applied thereto in use;   filling the at least one chamber with gel; and   attaching a backing to the polyurethane skin to enclose the at least one chamber.   
     
     
         11 . A method according to  claim 10 , further comprising providing a support structure to the backing and/or within the chamber.
